When the firmware detects a problem, it needs the host to stop/reset DMA and
resume it again when the hardware state has been reset.

MT7622 uses more interrupt bits for queue tx completion events.
Enabling those extra bits is harmless on MT7615

MT7615 supports dual-wiphy which means that it can run on 2.4G and 5GHz
channels simultaneously, and driver should configure each band.
Add missing register settings, and refine band related definitions to
avoid duplicate codes.

Add some sanity checks to the programmed values, because the firmware

- Store the previous and current rate set in the driver + the TSF value
at the time of the switch.
- Use the tx status TSF value to determine which rate set needs to be used
as reference.
- Report only short or long GI rates for a single status event, not a mix.
- The hardware reports the last used rate index. Use it along with the
retry count to figure out what rate was used for the first attempt.
- Use the same retry count value for all rate slots to make this calculation
work.
- Derive the probe rate from the current rateset instead of the skb cb
- Do not wait for a status report for the probe frame before removing the
probe rate from the rate table. Do it immediately after it was referenced
in a tx status report.
- Use the first half of the first rate retry budget for the probe rate
in order to avoid using too many retries on that rate
- Switch from lower rates to higher rates more conservatively
- enable hardware rate up/down selection

This driver is for a newer generation of MediaTek MT7615 4x4 802.11ac
PCIe-based chipsets, which support wave2 MU-MIMO up to 4 users/group
and also support up to 160MHz bandwidth.
The driver fully supports AP, station and monitor mode.
